No, it is a Fe-sulfide, not an Fe-oxide (= rust)

silvers turn black due to the reaction of sulphur present in hydrogen sulphide from air. --- Tarnish is silver oxide (rust) caused by a chemical reaction of oxygen and hydrogen sulphide with the surface of the silver. Unlike iron, silver will not rust in air absent of hydrogen sulphide.
Iron sulfide is a compound.
Yes. This is an example of the law of conservation of matter/mass.

iron sulphide is FeS while rust is oxide of iron Fe2O3.
Many, including Iron Sulphate, Sulphide, Oxide (rust) and more
Iron and sulphur make iron sulphide
Iron(II) sulphide: FeS. Iron sulphide is a synonym, but the first expression is more correct. Iron(III) sulphide: Fe2S3. Other forms of natural iron sulphides are known: see the link below.
The two possible formulaunits for Iron Sulfide are; FeS, and Fe1S1
iron sulphide, iron(II) sulphide or ferrous sulphide. Iron sulphide is ambiguous however and could refer to any one of a range of iron sulphur compounds,including Fe3S4 and Fe2S3

Iron sulphide is an ionic compound. The Iron is in a +2 oxidation state and the sulphur is in a -2 oxidation state.
